I tested a physical S5 and an emulated S5 Mini (via BrowserStack). The stereoscopic mode worked on the S5 but WebGL was disabled on the S5 Mini emulator, so I couldn't test any further. Do models in "regular" mode work for you?

@James, Yes I tested the model om various physical devices. The s4 (GT-I9500) Works fine with VR, so does the Iphone 4. The s5 mini (SM-G800F) and the Huawei P6 both have problems with VR. All phones do however show the regular model.

Hy guys, to add to the info. The Huawei P6 I tested was on Android 4.3. The S5 Mini was on Android 4.4.2
I tought it would be memory related. But if Julian's running A P8 with Lollipop that doesn't seem to be the issue..

i guess i got the solution thanks to an automated mail by yours.
My model has only been uploaded which did not allow me to use the cardboard function.
now i got a mail which remembered me to also publish the uploaded model and see .. cardboard-view is working fine!

The tutorial says "Insert your smartphone in a Google Cardboard or a similar smartphone based headset (e.g Samsung Gear VR)Insert your smartphone in a Google Cardboard or a similar smartphone based headset (e.g Samsung Gear VR)"
As far as I know there is no way of accesing the Samsung Gear VR outside of the Oculus store? Am I missing something here, because the first thing that happens when you insert the phone into the Gear VR headset is that the native app opens, hence you no longer see the Sketchfab VR.

Hi, I am having trouble looking at my model with a DK2. I published it and it works fine for an iphone with cardboard. When I try to view it on Nightly with my DK2 it recognizes the DK2 and the light turns on, but the image is black once I get past the warning screen. Do you know what could be going wrong?

Hi - I'm attempting to view various SketchFab models on my mobile phone (Moto X w/ Lollipop in Chrome) but the website is stuck in Portrait orientation. Even when I hold my phone in Landscape, and go into Full-screen I get a Portrait VR experience which won't work w/ my Google Cardboard. Any recommendations?

@James - User error, I had "Portrait Lock" on for my phone, I accidentally set that when adjusting my screen brightness settings. I have run into a few other issues though:

1. Switching to VR mode will very often move my camera to a completely different location, using Set/Save View for Orbit or First Person doesn't seem to work.2. VR Mode still accepts finger input, which means that my camera will move as a result of putting it into my Google Cardboard.3. Sometimes the VR head movement shifts from a FPS style movement, to a very disconcerting orbit-style movement.4. "Front" seems to be locked as opposed to being set when I switch to VR mode, which means I sometimes have to spin 180 degrees to get back the viewpoint I had when I made the switch. (Possibly related to #1)

The prospect of < 1min from my content creation app to a web-based VR viewer on my phone is amazing, but it doesn't seem like that's a reality just yet. Or - hopefully - this is even more user error on my part!
